18QHTF21-36.670-PD

Oscillators Overview

The 18QHTF21-36.670-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 36.67 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby power-down mode to reduce energy consumption during inactive periods. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0mm by 1.6mm. The component supports an operating temperature range suitable for industrial applications.

Oscillators Feature Summary

• Supports low voltage operation at 1.8V
• Includes standby power-down functionality
• Utilizes LVCMOS output interface

Oscillators Applications

• Embedded systems requiring precise clock signals
• Consumer electronics with space constraints
• Industrial control modules

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to avoid assembly issues.

Oscillators Selection Notes

Choose this model when a small form factor is critical for the application. The LVCMOS output is suitable for direct interfacing with digital logic circuits. Consider the power-down feature if energy efficiency is a priority for battery-operated devices.

Oscillators Part Context

This part belongs to the QHT series of surface-mount oscillators from Mercury Electronics. The series is known for providing stable frequency generation in compact packages. The 'PD' suffix indicates the inclusion of a power-down pin or function, distinguishing it from continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 36.67 MHz frequency, 1.8V supply, and LVCMOS output. Verify package compatibility with the 2.0x1.6mm footprint. Cross-reference with other Mercury Electronics models in the same series for potential alternatives.
